Human presence impacts fungal diversity of inflated lunar/Mars analog habitat.

This research paper explores how different types of fungi grow over time, particularly focusing on their presence before and after a crew arrives at an Antarctic base. To do this, scientists collected samples from various locations within the station's environment using special containers designed to prevent microbial contamination-a common concern when dealing with biological materials in such settings. The fungi were then carefully packed and sent back for analysis at a university lab where they underwent genetic testing, specifically looking into their DNA sequences known as ITS (Internal Transcribed Spacer). This helped the researchers identify various species of fungi present on different days and in specific areas within the station. Interestingly, some types of fungi became more abundant after people arrived at the base-a phenomenon that could have implications for cleanliness and health standards aboard such isolated environments as Antarctica's research stations. The study provides valuable insights into how human presence can affect microbial life in these unique settings, which is crucial information when considering hygiene practices to maintain a safe living space on the continent.

This research paper presents a comprehensive study on biological materials associated with macrofoam, focusing particularly on microbial contamination risks. The methodology involved collecting fungal samples from various locations over different days and times to assess the impact of crew occupancy on environmental sampling devices (macrofoams). The researchers employed a non-metric multidimensional scaling (NMDS) approach, specifically using metaMDS(dist_matrix,wascores=FALSE,zerodist="add"), for vector and curve fitting to analyze the microbial communities. The fungal samples were then coded with metadata before being stored at 4 °C until analysis could be performed on-site at the University of North Dakota (UND). Key findings revealed an increase in certain abundant families, such as Davidiellaceae and Hypocreaceae, from time points T0 to T30. This suggests that microbial communities within macrofoams can change over time with varying environmental conditions or human presence.
